以往的研究曾指出催产素在体外能刺激胎膜组织产生前列腺素(PG),但催产素引产成功者却并无羊水中 PG 的显著升高。为此作者用 Sep-Pak药针连续抽取选择性剖腹产(8例)、正常分娩(13例)、催产素静脉点滴引产(8例)及阴道PG片剂引产(8例)病例的脐带血、羊水和血浆,测定其催产素水平,以了解这类肽类激素在发动临产 Previous studies have pointed out that oxytocin can stimulate prostaglandin (PG) production in fetal membranes in vitro, but the successful induction of oxytocin but no significant increase in amniotic fluid PG. To this end, the author used Sep-Pak needle continuous extraction of selective caesarean section (8 cases), normal delivery (13 cases), oxytocin intravenous drip induction (8 cases) and vaginal PG tablet induced abortion (8 cases) Amniotic fluid and plasma, measured oxytocin levels to understand the type of peptide hormone in the start of labor
